As soon as you know you will not be able to have the test done, call the office at (336) 273-9297, extension 304, and speak with the scheduler about changing your test date.  Please note that patients scheduled for a Cardiolite (nuclear scan) test must give a 48-hour notice of cancellation so the medication for the test can be cancelled and a charge not incurred.  Our office contacts the referring doctor's office when a patient does not reschedule a test.
